Letters Patent No. 109,927, dated December 5, 1870.

IMPROVEMENT m THILL-COUPLINGSI.

The Schedule referred to in these Letters Patent and of the nine.

To all whom. it may concern:

Be it known that I, FRANCIS-B. Monsmof Plantsville, in the county of Hartford and'State ot' Connecticut, have invented a. new,Improvement in Carriage- Shackles; and I do hereby declare the following, when taken in connection with the accompanying drawing and the letters of reference marked thereon, to he a full, clear, and exact description ofv the same, and which said drawing constitutes part of this specification, and represents in- 1 Figure 1, a side view Figure 2, a top View Figure 3, a central section and in Figure 4, atop view of the shackle, thethil'l-iron' removed.

This invention relates to an improvement in device for attaching the thill or pole of carriages to axles, known to the trade as carriage-shackles, the olxject being, first, tosecure theanti-rattling pad in position; and secondly, a device for shifting for either pole or shafts without removing the eye from tho" shackle. I

My invention consists First, in forming a rib in each angle of the shackle, which imbeds itself into the IudiEF-rubber pad, thereby securing the pad, to prevent its accidental removal. I 1

.Second, in making the thill-iron and eye in two parts, with a threaded sleeve, tosecure the two parts together, and allow the thill-irons to be detached without reinoviug'the eye from the shackle.

A is the clip, upon which the base B and its'two ears, 0 O, of thc shackle, are formed iu.auy known manner. r

' The eye is inserted between the cars, leaving a space to be filled by the anti-rattling pad D, usually formed of India rubber. v

The working of the eye causes the pad to work out from its seat, to avoid which I form in ach angle of the shackle a rib, a, which imbeds itsclf'into the pad I), as seen in figs. 2 and 3, and thus prevents the dis placement of thepad.

- To removethc shafts or pole from the carriage, to change one for the other, orfor any other purpose, it

thill-iron being the same whether for shafts or pole,

and I out a thread on the meeting end of both parts, onto which an internally-tln'ezuled sleeve, I, is turned, say first onto the eye E, as denoted in broken lines,

fig. 3, then set the thill-iron in position, and run theslecvel onto the thill-iron, as denoted in'figs. 1, 2, and 3, coupling the two parts together. -\Vl1enever itisdesired to remove the shaft or pole, runthc sleeve I down onto the eye until the iron F is freed, when it may he removed and others attached or replaced when desired.

In order to take the strain from the thread of the screw, which in some cases is desirable, Iform a stud (l on the eye, as seen in fig. 3, making the shoulder on 'the eye, and the corresponding snrfitce on the iron, at

an angleacross the-threads, and the stud at right angles to the said shoulder. In consequence of this angular position of the stud, the strain upon the thill-iron isbrought upon the stud, which it must displace before the strain can come upon the thread, the

parts fitting closely together to give a combined strength far in excess of thethread alone.

'I claim as my invention- 1. A carriage-shackle in which the ribs (Ht are constructcd and arranged in internal angles to he imbeded into the pad D, in the manner and for the purpose specified.

2. The thill-iron Fahd eye E, combined with and united by the sleeve I, with or without the inclined stud d, substantially as herein set forth.
